VMware VAAI Storage Array Support in Plain English

February 8, 2011 By Stephen 18 Comments

The most exciting enhancements in VMware vSphere 4.1 is the addition of vStorage API for Array Integration (VAAI). This new API allows VMware ESX to offload storage processing functions to capable storage arrays, reducing the workload on the server hardware in introducing new and exciting possibilities for performance and efficiency. VAAI in ESX 4.1 includes three separate capabilities: block zeroing, full copy, and hardware assisted locking.

EMC Taunts NetApp: Counting Coup or Poor Sportsmanship?

January 18, 2011 By Stephen 16 Comments

Today was a big one for EMC, with the company launching or updating 41 storage products, including the new VNX storage system. EMC’s press and analyst event was equally notable, with a large crowd of insiders (including me) brought to New York City to watch a sideshow of world records set. Although Wall Street noticed all the fuss and rewarded the company with a 52-week high stock price, some actions away from the Equitable Center drew the ire of EMC competitor, NetApp.

Back From the Pile: Interesting Links, January 7, 2011

January 7, 2011 By Stephen Leave a Comment

It’s been a slow week (the holidays) and a crazy one. I’ve started pouring out the thin provisioning series, with 10 posts so far, as well as launching a new video “talk show” about enterprise IT. And I’ve got a new post over at SearchStorage, too. Whew!

GPS Time Rollover Failures Keep Happening (But They’re Almost Done)

This is week “1111111111” in the GPS system. Tomorrow morning it will roll over to week “0000000000”. How well will various systems handle this change? Not well, judging by what we’ve seen so far!

Ranting and Raving About the 2018 iPad Pro

I remain enthusiastic about the iPad Pro, despite getting a scratched screen and my concerns about durability. It’s a worthy successor to the original and offers enough improvements that I’d recommend the upgrade for just about anyone who uses their iPad for serious work. It’s still not yet a laptop replacement, but this is due more to a lack of desktop-class software for iOS than anything in Apple’s control.

SMB 3 is Going to be Huge, in both Scope and Impact

May 6, 2012

Microsoft is about to release the third major revision to their ubiquitous network storage protocol, SMB. Windows Server 2012 and Hyper-V 3 will really highlight this technology, and I predict it will transform the way people think about networked storage for Windows systems. But SMB 3 is big in another way, too: there are tons of new features, and not all will be implemented by everyone.

Top VMware Blogs 2014: How I Voted

February 25, 2014

Once again, it’s time for vSphere-Land.com’s “Top vBlog” voting. And once again Feedbin and Twitter are full of hundreds of bloggers lamely begging for me to vote for them. And once again, I didn’t base my votes on their begs or my own hunches. Follow along as I explain how I actually voted and why I think you should use the same mechanism. And no, I’m not going to say who I voted for!

The Myths of Standardization

December 15, 2011

I certainly benefit from standardization of the world around me, and I welcome interoperability and interchangeability as well as the price and product selection advantages. But I am not blithely focused on standardization above all else. I will happily use a proprietary solution if the alternative is inelegant, ineffective, or insufficient.

Virtual Machine Mobility: Of What, and to Where and in What State?

January 16, 2012

Moving cold virtual machine images from system to system, or even across great distances, is one of the main selling points of server virtualization. But it becomes much more difficult to manage movement of virtual machines that are still running, especially outside cluster or across WAN links. When talking about virtual machine mobility, it is important to consider what is being moved, the state it is in, and where it is going.

Why I Am Biased Against FCoE

October 21, 2011

I am biased against FCoE because it’s too new to be blithely and broadly recommended for production enterprise use. That’s all. Yes, the standards are standardized and there are products extant. But that’s not enough for me.

Generation 3 drobo: Fall In Love All Over Again

April 9, 2015

I remain a huge fan of drobo generally, and the third-generation drobo remains the best choice for home storage. It’s the perfect storage device for the long haul, and the performance improvements make it a no-brainer. Get one.

A Fairy Tale of Two Storage Protocols

September 23, 2014

It’s clear how this fairy tale ends. So many companies are using “S3 plus” as their standard interface, and even inside their solutions, that it’s safe to say it’s won the cloud storage API battle. But S3 isn’t a finalized spec – the industry will extend and improve it over the coming years. Soon we’ll have a cloud storage standard based on S3, just like we have a LAN file services standard based on CIFS.

Co-Processors, GPGPU, and Heterogeneous Computing

June 26, 2017

I’ve been thinking a lot lately about microprocessors, from the many-core CPUs that AMD and Intel introduced recently to the massively scalable GPGPU processing that’s taking machine learning by storm. After years of consolidation on commodity x86 CPUs, it seems that the computing paradigm is turning again to specialized offload processors. This trend towards heterogeneous computing will change the face of hardware, from mobile devices to the datacenter.
